Conversely, when I was in engineering school and working in a group on an project, and we wanted a late-night snack, just for laughs we would often demand that the pizza be cut into a certain number of slices that meant we wouldn't have to fight over the last one, but generally also meant you couldn't just run the cutter across the diameter three or four times.
Easy enough calculation for us engineers, but it was always a treat to watch the arts students who worked at the pizza place try to work out how to slice a pizza into, say, 15 pieces.
(Then I became an arts student, and it didn't seem so funny anymore.)
If only pie were square...
That's easy. Cut it into the normal eighths and then split all but one piece in half. Your bad project specification didn't say all 15 had to be the same size. :-)
Maybe pizza restaurants should be like the one on Breaking Bad which doesn't cut the pizza and passes the savings on to you. One of the commentaries said the writers added that after people complained about a scene where Walt threw a pizza onto his roof in a fit of anger and it hadn't been cut.
